Copying Multiple Documents from One Library to Another Using SP Designer Workflow

I am having an issue trying to create a copy of multiple documents within a library to another library. I am using Copylistitem within SP Designer 2010 and created a calculated column called "NextReviewDate" which just uses the "Approval Date" column plus "x" amount of days.

It works if there is only one document to move. However, if there are multiple documents, let's say Doc1, Doc2, Doc3, it is only copying Doc1 three times and adding the current date and time to the filename.
